Oral problems are also something that older people need to deal with proactively, knowing that periodontal disease and caries are most prevalent at ages 55 and above. However, that age group happens to be the high incidence of high blood pressure and heart disease, and these risk factors may increase the risk of tooth extraction. General cardiovascular disease patients can be extracted, but only before the extraction of teeth to understand the high and low blood pressure, the nature of heart disease and medical history. Cardiovascular disease patients have 7 attention to tooth extraction: 1, the elderly should be more cautious, people over 70 years old with cardiovascular disease on the extraction of the tolerance is worse, more chances of danger, whether the need for tooth extraction, should be fully considered before deciding. 2, nervousness can make 36% of the people with increased blood pressure, 63% of the people with arrhythmia, 12% of the people with ischemic electrocardiogram changes. Therefore, before the extraction of teeth should dispel concerns, do not be overly nervous. Taking tranquilizers such as Valium, Luminal and other drugs for the heart such as Cardioplegia can help eliminate the effects of mental tension. 3, tooth extraction time more than 5 minutes, 17% of people’s heart rate significantly accelerated, 37% of people’s blood pressure increased, 65% of people’s cardiac arrhythmia, 14% of people have ischemic electrocardiogram changes. This requires operation by skilled doctors and good cooperation of patients, striving to be completed within 5 minutes. 4. Observation shows that when the anesthesia effect is not good, it can make 42% of the people with elevated blood pressure and 55% of the people with arrhythmia. At present, it is believed that the effect of lidocaine local anesthesia is better, and painless tooth extraction can be achieved after sufficient anesthesia, which is safer. 5.Blood pressure, if more than 180/100mmHg, should be the first antihypertensive treatment. At the same time, the patient should relieve the worries and stabilize the mood, and then extract the teeth. Some patients who are overly nervous will have a sudden rise in blood pressure. 6, for people with heart disease, should first determine the nature of heart disease, is congenital heart disease, rheumatic heart disease, myocarditis or coronary heart disease. Rheumatic heart disease and myocarditis patients should pay special attention to tooth extraction, because tooth extraction may cause temporary bacteremia, tooth extraction should be injected with antimicrobial agents 2~3 days before extraction, in order to prevent the induction of bacterial endocarditis. Patients with angina pectoris, myocardial infarction history of tooth extraction, should also be careful, should take vasodilator drugs before extraction. 7, hypertensive patients are prone to bleeding after tooth extraction, should pay attention to pressure bleeding and application of antihypertensive, hemostatic drugs after tooth extraction. In addition, if hypertensive patients have heart, brain, kidney and other organs lesions or heart disease patients have heart failure, can not be extracted. Patients with high blood pressure and coronary heart disease should not extract teeth on an empty stomach to avoid fainting, and should not eat too much, which will aggravate the burden on the heart. It is recommended to rest for half an hour after tooth extraction before leaving the hospital. Elderly patients with cardiovascular disease is best to consult the attending physician to see if their own conditions are suitable for tooth extraction.
